Just had a new three-tab put on -- it's only been 37 years, but thought what the heck!
Walked the roof yesterday and notice that on three different tabs in different areas damaged shingles....basically, the granular top surface has been sort of "pushed away" to one side on the surface of the shingles, leaving the "tar paper" backing of the shingle exposed.
There is no hole through the shingle and these are NOT large spots. They appear only on one tab of the three and spots are about the size of a quarter or a fifty-cent piece. And, as I say, all-in-all only in three widely varying locations. Almost like a shoe ground into them at one spot (it was about 78 degrees the day they did the install, so they were hot).
I am assuming I should call them back to replace these, since it's beyond my ability, even though I know the "theory" on prying up etc. Plus, I have no extra shingles....
But, just wanted to check and make sure I'm not being too picky about this.
